Application filed January 3, 19 25;; $eria1 mi. 376;

My invention relates to heaters or stoves which employ gas as a fuel and are commonly used for heating residences.

One object of my invention is to provide an improved manner of holding the backwall and other parts in assembled relation in heaters of the radiant type.

Still another object of my invention is to simplify and improve generally the construction of stoves of the type referred to.

One form which my invention may take is.

shown in the accompanying drawing, wherein Fig. 1 is an elevational view of a stove embodying my invention; Fig. 2 is a cross sectional view thereof; Fig. 3 is a front elevational view showing particularly the form of baclcwall which I employ; Fig. 4 is a horizontal sectional View of the stove, and Fig. 5 is an elevational sectional view of a portion of the heater showing the manner in which the back-wall is supported.

The stove is provided with a lower rear plate 6 and end plates 7 preferably of castiron, the end plates being extended downwardly as indicated at 8, to form the rear legs of the stove. The lower rear plate 6 is provided with integral ears 9 that have holes for the reception of screws 10 which make screw-threaded engagement with the inturned angles of the end plates 7 to secure said plates together.

An upper rear plate 11 is provided, for tying the upper ends of the sides 7 together, and has lugs 12 corresponding to the lugs 10 of the plate 6, which are secured to the end plates 7 in substantially the same manner as are the lugs 9. The upper plate 11 is further provided with a flue opening 13.

The end plates 7 are each provided with a rib lt upon which the ends of a back-wall 15 rest, as shown more clearly in Figs. &' and 5. The backwall is preferably of refractory material such as clay, and is provided with an overhanging portion 16 which extends along the upper edge thereof and with end-wall portions 17 that rest upon the ribs 14 heretofore referred to. The baolcwall is also provided with an opening communicating with the flue opening 13, so that burnt gases may be directed therethrough by the overhanging portion 16.

vwardly and joined by an upper face plate 23 secured to the front plate 19 and the columns mast;

rear arise At the forward edges of the end walls 7 they are secured to columns 21, by means of bolts 20. The front plate 19 is provided with legs 22 that constitute the front legs of the stove. The columns 21 are continued upextending across the ends and the portion 16 of the back-wall 15. Webs or plates 24 may be 21 in any desired manner, to give a finished appearance. Similarly the legs 22 and the 1 columns 21 are provided with cap pieces or crowns to enhance the appearance of the stove.

Ahearth-plate 25iis bolted to the horizontal flange 26 of the plate 19, as shown more clearly in Figs. 2 and 4:. The hearth-plate is preferably of porcelain-enameled cast iron and serves not only to support the radiants or burner tubes as hereinafter explained, but also covers and protects adjacent portions of the face plate from the action of the heat. The hearth-plate is provided with a series of lugs 27 that form pockets for the reception of the lower ends of the radiants.

The burner consists of a fuel-pipe 29 mounted adjacent to the rear edge of the hearth-plate 25 and having a plurality of pairs of burner openings 30.

The lower edge of the back-wall 15 is spaced rearwardly of the burner tubes 29 so that an air passage '31 (Fig. 2) is provided therebetween. The tubes or radiants 33 may be of somewhat the usual form, and at their front lower edges fit between the lugs 27. I preferably provide no support for the rear edges of the radiants, since by supporting them at their front edges only, upon the hearth-plate, they tend to lean backward and thus bear against the back-plate 15, which'is the position it is desired they shall occupy. Should the stove he accidentally tilted forward the overhanging member 16 will prevent their falling out of the stove.

The back-wall is provided with a plurality of lugs 35 which hold the radiants in spaced relation to the main bodyof the wallso that air entering through the passage 31 may pass freely up behind the radiants and enter them through the openings 36 with which each radiant is provided, thus assisting in combustion of the gas which flows up through" the radiants from the burner opening 30. Lugs 37 are provided on the ends of the backwall to properly position the end radiants.

I claim as my invention:

1. A stove comprising end walls each having a horizontal rib, a backwall supported at each end upon one of said ribs, and a tie plate secured at each end to one of said end Walls for holding them in assembled relation.

2. A stove comprising end walls each having a horizontal rib,- a backwall supported at each end upon one of said ribs, a tie plate secured at each end to one of said end walls for holding them in assembled relation and disposed rearwardly of the backwall, and a tie plate connected to said walls and disposed forwardly of the back wall.

3. A stove comprisin end walls having horizontally-disposed ri s, a backwall sup ported on said ribs, a tie plate connecting the lower portion of said end walls, and a tie plate connecting the upper portions of said walls.

In testimony whereof I, the said ALEXAN- DER B. SHARP, have hereunto set my hand.

ALEXANDER B. SHARP.
